摘要：
Computer modeling methods predict that the natural zeolite laumontite will undergo pressure-induced hydration. Specifically, the water-poor analogue "leonhardite" transforms to the fully hydrated laumontite structure (see picture), a transformation with significant geochemical impact. The models and methodologies employed are also capable of replicating the observed dehydration behavior of laumontite.
